CCH — Cucumis melo

Summary

MELO3C009672.2, designated CmCCH, encodes a protein with N-terminal glutamine amidohydrolase activity (EC 3.5.1.122), magnesium chelatase activity, superoxide dismutase copper carrier activity, and calcium-dependent protein serine/threonine kinase activity. It is associated with chlorophyll metabolism and biosynthesis, regulation of stomatal opening, guard cell fate commitment, and responses to low humidity, carbon dioxide, and absence of light. The gene is linked to traits including seed yield, biomass yield, water use efficiency, transpiration rate, submergence tolerance, carotenoid content, jasmonic acid content, flowering time, germination rate, and disease tolerance. It localizes to the chloroplast inner membrane, thylakoid, envelope, stroma, and plastid, as well as the magnesium chelatase complex, mitochondria, apoplast, and cytosol. Related genes in other species are linked to retrograde signaling, chloroplast development, and ABA perception.
